Does anyone know what the cause of this might be, or how to remedy it? I've also experienced this problem with DivA, but I think that might also be using the QT codec.

The QT codec is simply interpolating the horizontal pixels, whether it be 360 or 480 of them, to fit in a 720 horizontal pixel resolution. I'm assuming it must repeat every other pixel or something similar.
My RealMagic Hollywood+ card in my PC that I use for viewing Prelinger's (and others) MPEG-2s on my TV set does this exact same interpolating with the horiz. resolution, slightly noticeable vertical lines that look exactly the same as the example framegrab you've posted a link to.
I dunno if there's a way around this, since the codec is trying to scale the res. of the MPEG-2 files up to standard MPEG-2/DV resoultion, by way of pixel interpolation...
